Application filed January 12, 1914. Serial No. 811,714.

To all whom it may concern:

Be it known that I, WILLIAM (humans, a citizen of the United States,residing at Kewaunee, in the county of Kewaunee and State of Wisconsin,have invented a new and useful Improvement in Milk-Can Bodies andRemovable Tops, of which the following is a specification.

This invention relates to a closure deyice for milk cans and. the objectof the device is to form a tight joint between the can and the cover,thereby avoiding the splashing of milk or cream from the can duringtransportation or while being handled. This resuit is obtained both byconstructing the can in such manner that the milk or cream thrownupwardly by j arring or moving the can will be thrown toward the centralpor- 7 tion of the upper part of the can rather than in a vertical linetoward the top, and splashing is further avoided by making-a water tightjoint between the cover and the can.

Another object of the invention is to avoid the rusting of the cancommon in the cans of ordinary construction in which a flanged coverfits tightly within the neck of the can.

These cans are thinly coated with tin and after the cover has been inuse a comparatively short time the friction between the cover flange andthe neck of the can causes more or less of the tin coating to wear off,

-- and the exposed portions then rust, thus rendering the can unfit forfurther use as a milk receptacle. In my construction'the cover does notengage any portion of the interior of the can and there is no rubbingcontact between metallic parw.

In the accompanying drawings, Figure 1 is a vertical section through thecan and cover. Fig. 2 is a side elevation of the upper portion of thecan, the cover being broken away and a rubber ring shown in elevation.Fig. 3 is a plan view, a portion of the cover being broken away andbeing shown in section.

In the drawings, 1 represents the usual cylindrical can body to whichispermanently secured an upper port1on 2, the walls of which curveupwardly and inwardly so that any milk or cream thrown to the to of thecan during hauling over rough roar s :or while being handled in any waywill be thrown inwardly toward the vertical longi- .nular' groove 4 andfitting within said groove is a rubber rim 5. This ring is curved uponits inner slde to fit the transverse contour of the groove 4, but isprovided with a plane exterior face, and this exterior face vforms aslight angle with the longitudinal axis of the can, sloping slightlydownwardly and outwardly. A cover 6 is provided with flanges 7 whichhave the same inclination with the vertical axis of the can as theexterior face of the ring 5 and a wedging action is therefore producedwhen the cover 6 is fitted over the neck 3.

It will benoted that the flange 7 fits upon the outside of the can andengage the exterior plane face of the ring 5, and the farther the cover6 is pressed down the more tightly the wedging action of said flange andring will become.

It will be further noted that the frictional contact is entirely betweenthe inner face of the flange 7 and the exterior face of the ring 5 sothat there is no possibility of rubhing the tin coating off of anyportion of -terior annular groove, a rubber ring, the

inner face of which is rounded to conform.

to the transverse contour of said grants,-

and the outer face of which is a plane suit a face, said surfacebeing-,arranged at a siiight angle with respectto the vertical axis ofthe can and a cover having a flange adapted to fit over said ring,thesaid flange having an inclination with respect to the vertical axisof the can similar tothat of the plane surface of said ring, as and forthe purpose set forth." g g I i v WILLIAM GRANNIS.
